Mute the hearing aid
Use the mute function if you need to silence the
hearing aid. The mute function only mutes the
microphone(s) on the hearing aid.
Optional LED
Green and red blinks, continuously repeated,
indicate that mute is activated.
Important notice
Do not use the mute function as an off switch,
as the hearing aid still draws current from the
battery in this mode.
Apply a long press
(four seconds) to either end
of the button to mute the
hearing aid.
To reactivate, press the
button briefly.
